I have 2b wavy hair that is medium-fine, normal elasticity and normal porosity. I also cannot use wheat products so finding protein sprays that I can use is tough. this works great and I can use it a couple of times per week without overloading my hair. It perks up my waves. I can even use it on dry hair and see my waves perk. Just be careful not to spray on too much or your hair will feel a bit grimy and tangly.
